Done as a for fun project to have a 100% 3d printed filament spool. Worked much better than expected so decided to share.

Print two bearings and one each of the other parts. Fits on the stock Ender 3 V2 filament spool bracket.

0.20mm or smaller layer height suggested for bearings and threaded parts, the others can be larger layer height if desired.

Orient parts on bed prior to printing.

When assembling, leave some play when installing the retaining nut (smooth one for the end) or the spool will not easily rotate when. Mounting nut (hex nut) should be tight.
